WARNING
FLIGHT SAFETY PART
The link assembly and support bolt are flight safety parts. Failure to follow maintenance
instructions may result in serious injury or death of crewmembers and/or serious damage to
the helicopter.
Heat treated condition of the link assembly and support bolt is critical to its serviceability.
Any indication of heat oxidizing (discoloration), where visually detectable, requires replace-
ment of the part. This part must be protected from unscheduled heating and external impact
during inspection and handling procedures.
